I'm not sure how to do this after things have been already deleted but
if the goal is just doing a `secure' delete check out the -P switch of
rm. Although this is the old DoD standard of three overwrite passes,
I'm not sure if it's still as bullet proof as it once was. These days
modern computer forensics can still access data that has been
over-written numerous times.
